    OMG I think I have a tube going bad! I'm glad to have a tube pre but it has only 2 tubes. And it has had me wondering what I am hearing.

    Looks to me it has a set for each input. That is, one (set) for each of the aux, one for the MC phono stage, one for both MM phono stages, and one for each tape in. Shouldn't be too hard to trouble shoot.

    hmmmm, to kind of like have a tube buffer for every one of your sources.

    intersting, part of me says overkill, but interesting nonetheless

    Very intriguing :) . I can't say that I have ever run across a cascode arrangement using tubes ( in a pre no less). I know they are out there, but never really encountered one before. I am a big fan of the cascode arrangement with transistors (ie; Nelson Pass)

    Here are a couple articles. The first is one Nelson Pass wrote and although it's mostly about transistors the principles can be applied to tubes as well.

    http://www.passlabs.com/downloads/articles/cascode.pdf

    The other is simply a good Wikipedia explaination.

    http://en.wikipedia.org/wiki/Cascode

    Very interesting piece there Noel. To bad it would be so expensive to roll your favorite tubes, because otherwise it looks like a winner and a unique piece.

    If that's true, then I wouldn't have to have the best tubes in every socket. Just put my faves in the sockets for the inputs being utilized, correct? Put some cheapies in the others.

    if anthony is right, then yes, your right.

    if you listen to one source for a while, that sounds workable, bu if you switch sources alot, it might be a P.I.T.A. might be worth it though if it is that good a pre.

    I'd really check the design and see if that's the case (each bank being for each input). If it wasn't cascode Anthony is probably right, but since it's a more complicated design, I'd make sure before assuming. Just a thought

    I think I'll do a little more research on the Rogue Sixty-Six tubed pre. I like the looks and it has a remote.

    Anyone know anything about Rogue gear? Their stuff looks well built.

    I heard the Rogue Audio gear @ Decibel Audio (same place I demo'd the VS speakers). Great stuff but too pricey for me. The remote is a massive metal thing with an up arrow and a down arrow - thats it - basic.

    Crazy. That thing can hold more capacitance than many amps.
    Tube rolling would be very co$tly on that unit.

    Is Mark Hardy one and the same as mhardy6647? They are both from New England. Perhaps you could PM him Noel. I think they are the same person.

    Or you could set it up with the sound you like for each piece of equipment you use. Say you have a bright sounding CDP and want to tone it down a bit...

    Here's a copy and paste from the linked thread...
    "Cascode is a compound tube - which is to say, two tubes configured as one. In general one tube is used as a dynamic load to another tube used as the amplifier (instead of using a load resistor). This makes it possible to get the gain of a pentode from a triode while retaining all the linearity and transfer characteristics of a triode. Most early examples go back to Wallman in the '40s.
    mdeneen"

    Looks like you also have even more flexibility when it comes to tailoring your sound. You could use something neutral as the dynamic load and something warm and euphonic as amplification. Of course, that is if the above post from the Klipsch forum is correct.

    It's a quote from the designer, so I'd say it'd have to be correct.

    Noel, my McAlister ML-33 pre amp is set up like that. Two 6FQ7 tubes provide infinite plate load resistance for the two 6CG7 linestage tubes.

    Yes. If you haven't read the link to the Nelson Pass article on Cascode config. do so, it goes into more detail about how it works. It doesn't matter if it's tranny's or tubes the effect/outcome is the same. It's actually a pretty cool way to arrange an amplification circuit. That's why I like my Nak receiver so much. The Stasis amplification (which Nelson designed) works using the cascode principle, only on a smaller more compact scale than in his big amplifiers.

    Again nothing new here as this configuration was around in the 40's and 50's (for tubes) it's just todays implementation is much better, what with newer more reilable and exacting parts, etc. And it seems to overcome some pitfalls in common transistor output sections. You get many of the benefits of class A performance w/o the waste of as much energy. Plus you eliminate much of the unwanted side effects of too much negative feedback in A/B designs not to mention switching distortion, which in some cases can be detrimental.

    For tubes it's possible to get the gain of a pentode from a triode while retaining all the linearity and transfer characteristics of a triode.
